GeneDx RCV000213079 SCV000211816 pathogenic not provided 2018-07-03 criteria provided, single submitter clinical testing The R167W missense variant in the VHL gene has previously been reported in association with von Hippel-Lindau syndrome (VHL) (for examples, see Crossey et al., 1994; Matsuo et al., 2011; Zhang et al., 2015). Functional studies show R167W does not bind to elongin B or elongin C, resulting in an unstable protein that is rapidly degraded by the proteasome (Schoenfeld et al., 2000). The R167W variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved across species, and occurs within the alpha domain and the elongin C binding region (Yuen et al., 2009). Furthermore, missense variants in the same residue (R167G, R167Q, R167L) have been reported in the Human Gene Mutation Database in association with von Hippel-Lindau syndrome (Stenson et al., 2014), supporting the functional importance of this region of the protein. Based on currently available evidence, we consider R167W to be pathogenic.
Invitae RCV000627746 SCV000285500 pathogenic Erythrocytosis, familial, 2; Von Hippel-Lindau syndrome 2019-11-26 criteria provided, single submitter clinical testing This sequence change replaces arginine with tryptophan at codon 167 of the VHL protein (p.Arg167Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is present in population databases (rs5030820, ExAC 0.002%). This variant has been reported in individuals affected with von Hippel-Lindau syndrome and pheochromocytoma (PMID: 7987306, 12000816, 23512077, 19464396, 15300849). This variant has been reported to segregate with disease in families affected with von Hippel-Lindau syndrome (PMID: 25563310, 9829912). ClinVar contains an entry for this variant (Variation ID: 2218) Experimental studies have shown that VHL protein with this variant does not fully stabilize Jade-1, which is an important factor in renal tumor suppression (PMID: 14973063). Codon 167 is located in the alpha domain of the VHL protein and is reported to be important in maintaining protein structure. This codon is the most frequently mutated residue in the VHL gene, accounting for 46% of the mutations in patients with type 2 von Hippel-Lindau syndrome in one study (PMID: 22799452, 9829911). For these reasons, this variant has been classified as Pathogenic.
Integrated Genetics/Laboratory Corporation of America RCV000002302 SCV000697524 pathogenic Von Hippel-Lindau syndrome 2017-04-20 criteria provided, single submitter clinical testing Variant summary: The VHL c.499C>T (p.Arg167Trp) variant located in the alpha domain (via InterPro) involves the alteration of a conserved nucleotide and 5/5 in silico tools predict a damaging outcome. This variant was found in 1/121114 control chromosomes at a frequency of 0.0000083, which does not exceed the estimated maximal expected allele frequency of a pathogenic VHL variant (0.0000208). Multiple publications have cited the variant in affected individuals ranging in phenotypes from VHL, renal carcinoma, hemangioblastoma and pheochromocytoma. Functional study, Schoenfield_2000, indicates the variant disrupts the elongin binding capability to VHL, a function that is essential for the tumor suppressor function of VHL. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic.
